摘要： PROBLEM TO BE SOLVED: To provide a mounting structure for easily mounting a flexible joint between a tip part of a shielded tunnel and a peripheral edge part of a pit mouth of an arrival shaft by easy work, without putting the periphery of the pit mouth in an unstable state.
SOLUTION: This flexible joint 10 mounting structure is arranged in an annular ring shape by interposing between the tip part 15a of the shielded tunnel 15 joined to the arrival shaft 12 and the peripheral edge part 13a of the pit mouth 13 of the arrival shaft 12, and absorbs relative positional dislocation between the tip part 15a of the tunnel 15 and the pit mouth 13. The flexible joint 10 is composed of a segment side fixing part 16 fixed to the tip part 15a of the tunnel 15, a pit mouth side fixing part 17 fixed to the peripheral edge 13a of the pit mouth 13, and a flexibly deformable part 18 arranged between the segment side fixing part 16 and the pit mouth side fixing part 17. The segment side fixing part 16 is fixed to a cutting end surface 19 of cutting a segment 14a on the tip of the tunnel 15 in a design fixing position of the segment side fixing part 16.

摘要： PURPOSE:To prevent bending in the direction of excavation by connecting the outer end sections of a plurality of arms installed at the front end of a shaft and extended in the radial direction by a ring member and mounting excavating edges to the arms and the front of the ring member at intervals. CONSTITUTION:A ring member 11 is fixed onto the fronts of the outer end sections 10a of mutually continuous two arms 10 formed to an approximately fan-shaped plate form so that the outer end sections 10a are connected in the circumferential direction. Excavating edges 12a, 12b are projected forward in the axial direction at proper intervals to each of the arms 10 and the ring member 11, thus forming a cutter 9. A hood ring 15 completely housing the arms 10 and ring member 11 of the cutter 9 in the axial direction is fastened onto the front end face of the hood of a shield shell 1.

摘要： PURPOSE:To realize a method for preventing the bending of laser beam when measurement is performed by utilizing the laser beam by sending air having a constant temperature into a straight pipe wherein the laser beam passes, and maintaining the uniform temperature along the entire length and the entire space in the straight pipe. CONSTITUTION:A laser beam is projected on a photodetector 11 in a shield excavator 2 from a laser transmitter 10 which is provided in a starting vertical shaft 8 through the inside of an underground pipe 1. Whether the shield excavator 2 is directed toward the specified advancing direction or not is measured from the light receiving position. Thus, the excavation is performed. At this time, the temperature of the air in the buried pipe is high at the upper part and low at the lower part. The straight advance of the laser beam is impeded by the difference in temperatures. To eliminate the impedance, the air at the constant temperature is supplied to the underground pipe 1 from a blower 16 which is arranged in the starting vertical shaft 8. The temperature distribution in the buried pipe 1 is kept uniform by the air. Therefore, the laser beam from the laser transmitter 10 is uniformly projected on the photodetector 11 without bending in the buried pipe 1, and the survey and the measurement characterized by excellent accuracy can be performed.
